The autonomous robotic fish that can sense marine pollution

The SHOAL project is a collaboration between European universities, businesses, and the Spanish port of Gijon that has created autonomous robotic fish that can sense marine pollution.

With these fish we can find exactly what is causing the pollution and put a stop to it right away, says SHOAL project leader Luke Speller.

The robotic fish are equipped with a range of built-in sensors that detect lead, copper, and other contaminants, as well as measuring water salinity. If one of the fish senses pollution in an area, it calls others to help create a detailed map of high and low concentrations of the pollutant, enabling authorities to locate the source. The robotic fish are one--and-a-half meters long, have an eight-hour battery, and can communicate with each other and a nearby base station using very low-frequency sound waves. However, the robots also have a low data transmission rate and can only send short, predefined messages. "It's a good solution, but it requires thinking carefully about what data to transmit and how to use that data," says University of Washington roboticist Kristi Morgansen.
